Clinical Trial Summary

This is a single-group, observational study which will involve obtaining two echo scans of recruited patients. All recruited patients will undergo echo scans by both novice users (nurses) and experts (echo sonographers). Image quality between novices and experts as well as the ability to calculate LVEF from novice and expert scans and the quality of the LVEF calculated via KOSMOS-EF compared to LVEF calculations by expert cardiologists will occur in post-hoc Echo image analysis

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessment of Global Left Ventricular Function	A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurses is of sufficient image quality to make a qualitative visual assessment of the Global Left Ventricular Function.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Primary	Assessment of Left Ventricular Size	A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurse is of sufficient image quality to make a qualitative visual assessment of the Left Ventricular Size.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Primary	Assessment of Non-Trivial Pericardial Effusion	A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurse is of sufficient image quality to make a qualitative visual assessment of Non-Trivial Pericardial Effusion.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Primary	Assessment of Right Ventricular Size	A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurse is of sufficient image quality to make a qualitative visual assessment of Right Ventricle Size.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Secondary	Assessment of Automatic Structure Labelling	A panel of cardiologists will access and determine via a majority vote if the frame-level false discovery rate (FDR) of automated cardiac structure labeling as determined by expert cardiologists for scans acquired by cardiac sonographers.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Secondary	Manual vs. KOSMOS-EF for Sonographer Scans	Measurements are computed for A4C and A2C scans acquired by sonographers . We will compare KOSMOS-EF LVEF calculation to LVEF calculated by a panel of cardiologists via a majority vote.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
Secondary	Assessment of Left Atrial Size	A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurse is of sufficient image quality to make a qualitative visual assessment of Left Atrial Size.	Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments
